We are beginning to get several reports about Fire Blight in Pear Trees.

Fire Blight is a problem in Apple, crabapple, pear, raspberry, blackberry, and pyracantha in Oklahoma.

Disease symptoms first appear when trees are blooming. The leaves on blighted terminals turn brown to black and usually remain firmly attached to the infected twig throughout the growing season. Blighted terminals usually take on a shephard's crook appearance.


Sanitation - The first step in a good control program starts with removal of all infected tissue as soon as it appears. During pruining activities, all cutting tools should be disinfected after each cut to prevent the spread of bacteria (use denatured alcohol or 10% bleach).

Cultivar Selection - No known cultivar of apple, pear, pyracantha, flowering crabapple, cotoneaster, quince, hawthorne, or rose is completely resistant to Fire Blight. However, some cultivars of these plants are more resistant or tolerant of Fire Blight than others. Therefore, if Fire Blight has been a problem in the past it may be beneficial to consider planting less susceptible cultivars.

Chemical Control - Several types of bacterial formulations, in conjunction with the previously described cultural practices, may be effective in prevention of the blossom blight and terminal blight stages of Fire Blight.

Love the response I’m getting out of this post! If I didn’t respond to your individual question, please message me directly!***

Let’s talk about SPURWEED! You’re probably just now noticing it in your yard, the seed heads which are stickers are starting to emerge. Unfortunately now is NOT the time to treat it!

Winter is the best time to kill spurweed, a.k.a. "stickers" in your yard with a broadleaf herbicide containing 2, 4-D.

RIGHT NOW: You can fertilize your grass to get it high enough to buffer the seeds (stickers), so you and the dogs can walk - but that's about it.

Spurweed is a winter annual weed that germinates in the fall, producing a ground-hugging plant with parsley-like leaves. It grows in the fall and winter, blooms with tiny white flowers in late winter to early spring, then sets the seed which is the problematic sticker.

This fall, either use a pre-emergent herbicide, or spray with a post-emergent herbicide with 2,4-D in it between December and February during your grass' dormant period while the winter annual weed is green and growing but hasn't had a chance to bloom and set seed. The spurweed seeds become the stickers and the stickers become painful for you and your pets.

There are numerous formulations of two and three way mixes of 2,4-D, dicamba and MCPP. Make sure you read the label before purchasing that they are safe for your particular southern grass. For instance, Bermuda tends to be more herbicide tolerant than St. Augustine or Centipede.

In summary: you can use a pre-emergent herbicide in mid October to mid November or you can wait for the weeds to germinate and then easily kill them with a broad leaf herbicide such as 2, 4-D somewhere in the time frame of December to February.

THE KEY IS TO MAKE THE APPLICATION EARLY ENOUGH IN THE WINTER SEASON TO PREVENT SEED SET! If you can do this, you will greatly reduce the population for next year, but if allowed to go unchecked, you will have more and more stickers each year!!!

Illinois producer Gray Tretter lost nine calves to black vulture attacks in 2018. Eyes pecked out and backsides torn to a bloody pulp, the calves were devoured alive. “I can’t imagine what the calves go through,” Tretter says. “A coyote or a big cat would be a much better way to go than the damn black vultures."

Cattle Producers will have the opportunity to become Beef Quality Assurance Certified on January 24th at a training held by the Pontotoc County Extension Office. The training will begin at 6 p.m. in the North Meeting Room of the Extension Office located at 1700 N. Broadway in Ada. The certification and meeting are free of charge and open to the public.

Beef Quality Assurance does more than just help beef producers capture more value from their market cattle: Beef Quality Assurance also reflects a positive public image and instills consumer confidence in the beef industry. When producers implement the best management practices of a Beef Quality Assurance program, they assure their market steers, heifers, cows, and bulls are the best they can be. Today, the stakes are even higher because of increased public attention on animal welfare. Beef Quality Assurance is valuable to all beef producers because it:
• Demonstrates commitment to food safety and quality.
• Safeguards the public image of the beef industry.
• Upholds consumer confidence in valuable beef products.
• Improves sale value of marketed beef cattle.
• Enhances herd profitability through better management


Private Pesticide Applicator packets are now available at the OSU Extension Office. They are $20 and require a take-home open-book exam. If you are successful in scoring 70% or higher, your license will be valid from Jan. 1,2019 to December 31, 2023.


Have you ever wondered why your calves did not top the market? What is a number 1 or number 2 calf, and what is the difference? What factors influence the selling price of cull cows? If you have ever wondered about any of these questions the Pontotoc County Cattlemen’s Association will be hosting a meeting on October 25, 2018 at the Southern Oklahoma Livestock Auction (SOLA) at 6 p.m. We will discuss the factors that greatly influence selling price of both cows and calves, as well as discuss some other important factors that could produce more money for your pocket.

It's that time of year again when we start getting questions about "Sage" grass in fields and how to control it. The past year or two has been favorable for this grass to grow and has been seen in fields that you normally wouldn't expect. Below is a great article by Brian Pugh that explains control methods for Broomsedge Bluestem.

Broomsedge Bluestem is an Opportunistic-Indicator Plant
Brian C. Pugh, OSU Area Agronomy Specialist

The grass that gives a lot of eastern Oklahoma pastures the bronze or copper colored appearance during the fall and winter is broomsedge bluestem, also known as “sage grass.” Broomsedge is a native grass that grows well on sites that have low fertility or pH. It is allelopathic, meaning it produces a toxin that inhibits the growth of other plants. Most animals will avoid grazing this plant except in the early spring and when other forage is not available. This explains why Broomsedge can become the dominant species in a pasture. Broomsedge is an opportunistic plant that takes advantage of poor fertility management and overgrazing. It also is a good indicator of needed management changes to the grazing system. A common question at most Extension offices is how to get rid of broomsedge bluestem.

Broomsedge is relatively short lived for a perennial grass. In fact, 50% of existing plants will only survive about three years, 90% are gone by year six and all plants will die by the age of seven. Anything that makes the desirable grasses more competitive and reduces the survival of new broomsedge seedlings will hasten the reduction of the broomsedge population. A 1936 study at a TN Ag Experiment Station found that the addition of needed N, P and K coupled with regular defoliation through intensive early grazing created competition from desirable grasses and reduced a 90% ground cover broomsedge stand to less than 5% cover within four years. This has been duplicated many times since then. Applications of lime in low pH soils have also shown reductions in broomsedge due to ensuing competition from desirable species.

Controlling broomsedge in introduced pastures, such as bermudagrass or fescue, is fairly easy but does require a little patience. Soil testing is the key and will reveal any deficiencies in P,K or a low pH. Correcting these deficiencies will go a long way towards rescuing the forage stand from broomsedge. Again, intensive grazing early in the year when broomsedge is moderately palatable to the animals will further stress the broomsedge plants into submission. Rotational stocking can also be used to force animals to graze broomsedge in the spring and early summer.

Controlling broomsedge in native range sites is more difficult than in introduced grasses. In range sites we rely on cultural practices such as fire and grazing management to hopefully reduce or at least slow the spread of broomsedge bluestem. Native grasses do not respond efficiently to fertilizer like the introduced grasses. Therefore, the use of an intensive early stocking program to graze broomsedge, followed by resting the stand through the remainder of summer is beneficial. Rest allows our desirable native grasses an opportunity to restore lost energy and produce a healthier, more competitive stand. Native hay meadows should only be baled once per year to increase competition with broomsedge. Oklahoma research has shown a fall prescribed fire within 1-2 weeks of the killing frost is the best way to reduce broomsedge stands in native sites. This stresses the broomsedge plant during preparation for winter and burns seeds still on the plant. Don’t expect this method to work as fast as in introduced forages.

Again, remember that broomsedge is an indicator of improper management. Promoting our desirable forage species through fertility, lime, harvest strategy or fire will reduce the prevalence of this short-lived grassy nuisance in a few years.

Yesterday, I noticed several small twigs and limbs under my elm tree. With close inspection, I found that they had been girdled by these critters!! Anyone else seen these twig girdlers on elm, pecan, hickory or other hardwood trees?
